Green Energy Videos

Informative, how to, green energy videos may be placed on this page with a description and a link. All I need is your youtube small frame embed code, a link and a description. Your how to video should help us become more energy independent. Renewable green energy such as solar, wind and geothermal is the way of the future and I am hoping that together we can spread the word and help create a better world for ourselves and our children.

This is an experiment designed to demonstrate the relationship between collecting solar heat and storing solar heat. Notice that both bottles of water get hotter when the sun strikes them. The painted bottle gets hot faster but the felt covered bottle retains heat longer.

Modified Trickle Down solar heating was designed to lower the cost solar heating application for do-it-yourselfers. Modular collectors use inexpensive black polyester felt rather than expensive absorber plates and expensive flow tubes.

The downspout collector is a simple unobtrusive way of collecting solar heat as long as you have the sufficient sunlight on the south side of your house.

This 8' x 24' collector was built in place and mounted on poles on the ground. The absorber plates were made from aluminum fins and and the flow tube was made from 3/4" PEX. Scott will explain it to you.

How can we place a value on sunlight? In 2011 we say oil has a retail value of $4/gallon and electric power has a value of .$0.20/ KWH but how can we place a dollar value on sunlight? Can homemade solar applications save heat and actually provide a source of income?

Our Big Sun provides us with a direct connection to the energy from the universe. The dawn of a solar age has is here now and there will soon be many local green energy opportunities for everyone. Start small but think big like the sun.

The oblique rays of a January sun offer little warmth but if your collectors have a steep pitch and your not surrounded with trees it's possible to to solar heat your house in the dead of winter with a sunshed.

The efficiency of heat transfer can be improved by using multiple tanks designed to increase heat stratification. This method is used to trap hot water and return cold water to the collector.

The Solar Workshop has been designed to maximize both the work space and the surface area for heat collection and storage with a minimum of low cost materials. Heat storage drums are installed inside an insulated shed on the North side of the shop to conserve work space so that the south side of the shop is free to receive a winter's sun.

Direct connect solar hot water systems are connected directly with a homes hot water plumbing system so that heat transfer coils are not necessary. Direct connect systems are used in areas where freezing is not a problem. Drain down, direct connect systems have been used in cold climates, but if the emergency drain down fails freezing water could damage pipes.

The one LED differential controller uses thermistors to sense the differential temperature between collector and storage tank. It's a rugged little controller capable of regulating a 300 watt pump, but it only has one LED that comes on when the pump is activated.

The two LED differential controller is almost identical to the one to the left but it has an additional LED used to monitor heat availability. The red LED glows in proportion to the heat energy available and the green LED turns on when the pump is activated.
